Monsters and spice? What more does one need?
When I started, I had no clue as to where this story would end up. The writing and characters kept me engaged.
There is a plot to go along with the spice so for those that need story, it's got you.
I was reluctant to start this originally but eventually, after seeing so many others talking about it, I broke down and read it.
No regrets.

Wtf? Why did I like this?
Have you ever thought "I wonder what it would be like to become a shapeshifter so my body could accommodate increasingly larger monster schlongs and have free access to multiple supernatural species to handpick for my own personally designed orgies?"
No? Me either. Until now.
Cat lives an unful"filled"ife with these basic human schlongs. So when she is given an offer she can't refuse in the name of "Science!" she jumps head first into the opportunity. She is VERY eager to "test" each and every monster and can be very vocal and demanding. *You go Glen CoCo*
This book is 90% Smut. 10% story. And 125% "WTF did I just read?"
Read it. Just Do it. Someone else needs the image of a Centaur schlong going quite literally in one end and out the other, without killing anyone. YOU'RE WELCOME.

Science, Monsters, and Zero Respect for Anatomy.
Test Subject is easily one of the most ridiculous, entertaining things I’ve ever read, and Tami (the author) is genuinely hysterical. Her humor is so sharp and unhinged that I kept laughing mid-chapter like, “There’s no way she actually wrote that… oh wait. She did.” ("I feel like more cum than girl" is a personal fav lol)
The pacing? Impeccable chaos. Every door Kat opens is a new “surprise biology lesson,” and you truly never know what creature is waiting on the other side. The escalation is insane.
The final boss structure is honestly brilliant: she has to go in order because her body literally cannot handle skipping levels. Door 1 preps her for Door 2, which preps her for Door 3… all the way up to the Big Bad at Door 10. It’s like a monster-sex training regimen. Progression-based peril. I respect the vision.
And Kat is just out here doing her job like a pro. Clipboard in hand. Safety protocols ignored. Body being bent, stretched, and shape-shifted into configurations that aren't medically recognized (what do you mean she's being impaled and loving it?). Yet she stays committed to the work and making a difference.
In short:
If you want something funny, fast-paced, a little feral, and unlike anything you’ve ever read - this is your book.

Read it!!!!
This Is one of the best off the wall smut I’ve read in a while. The writer is insane! How did she even think about 90% of this stuff! I couldn’t imagine half! The creativity knows no bounds. It’s a very good read if you’re into taboo, monsters, magic and sexy time 😮💨!
The writer wasted no time and jumped right into the plot! 10/10 HIGHLY RECOMMEND!

hot and erotic
Couldn’t put it down. The storyline is great and the relationships even better. Must read. Absolutely worth the read. I’m sure I’ll read again.

Review of Test Subject by Tami
Test Subject is a short, fast-paced fantasy novel that blends dark romance, smut, and magical experimentation into one wild ride. The story follows Cat, a xenobiologist who accepts a mysterious position in an underground laboratory. Behind ten doors await ten different supernatural beings—an incubus, a djinn, centaurs, and more—each encounter pushing her further into a world of impossible desires and dangerous magic.
The premise is bold: Cat must engage with each creature in turn, ultimately facing a dragon whose survival depends on her willingness to mate and secure the continuation of his species. The book spans just over a week in Cat’s life, told across 18 chapters, and focuses tightly on her daily research tasks and the increasingly intense, fantastical encounters she experiences.
This is not a story for the faint of heart—it revels in the bizarre, the erotic, and the downright impossible. But that’s also its charm. If you enjoy short novels packed with fantasy creatures, magical settings, and unapologetically smutty scenarios, Test Subject delivers exactly that. It’s quick to read, imaginative in its creature design, and unafraid to dive headfirst into dark romance territory.
For fans of fantasy, magic, and unconventional romance who don’t mind things getting a little outrageous, this book is a fun, indulgent escape.

I just read the book and the other reviews here and I completely understood why so many people praise it. It’s chaotic, entertaining, and full of wild monster-fantasy moments that kept me turning the pages. I loved how unpredictable it was. Every time you think I know what will happen next, a new “door” brought something surprising and fun. The book absolutely delivers on the spicy, bizarre energy readers talk about. At the same time, I personally enjoy stories that have a bit more depth and world-building. While the book was a great, guilty-pleasure read, it didn’t fully satisfy my craving for a richer plot. Still, I genuinely enjoyed the ride and would recommend it to anyone who wants something bold, fast, and outrageous!

Steamy Monster Erotica
I really enjoyed the reading. The sexy scenes were very descriptive and left me wanting to read more. This is a two in one book, so you get two parts.
Some parts were very creative but I wasn’t expecting reality and all sorts of kinks are included. Decent storyline but minimal plot which is expected.

Let's be real everyone wants to know about the monster stuff, and I can assure any interested reader that the spicy scenes in this book are earth-shattering, unhinged, wild romps of pure delight. I mean, there are acts described in this book that even a seasoned smut reader would be blush. There's a chapter called "The Impaling" that has changed my brain chemistry.
But insane spice is not the point of my review--I am here to talk about how magic works in this series. Without giving any of the plot away, this book treats magic not like an outside force or something innate to a person, but rather treats it like a virus. Magic is something that can be acquired through physical contact and (like a cold or flu) presents slightly different in each person. I was quite frankly blown away at the creativity here--it takes something so basic to fantasy world building and opens it up completely. The world building that this implies and builds on keeps readers engaged and intrgued, on top of just being there for the monster sex.
TLDR: Come for unhinged monster realtions, stay for the most innovative magic system.

It is…. different, but somehow similar to watching a train wreck it had me enthralled…. And it’s odd because nothing about the random and weird activities in this book would be remotely appealing had they not been presented how they were…. Had you not got to know Cat as an unfulfilled woman seeking something to fill the emptiness inside of her that was never quenched by the normal cures.

I read this on Galatea and it was really good! I wish there was more plot though, but good nonetheless! I’m reading the second book now.
Definitely be careful of the triggers though, cuz there is one chapter that can be really triggering to some… if you figure out the chapter tho, u can skip over it without it effecting the quality of the book.

No limits. All monster d*ck.
I am not sure what this book is. It is like someone really horny with no sexual limits made a book that was sexually denied for a long time and their imagination ran wild.

Smut From Start to Finish
Least realistic smut I’ve ever read in my life, but it’s spicy all the way through. Points for creativity. I loved it. Finished it in a day.

This was a fun book. It had a vibe of goldilocks and the monster dicks.
It does require a heavy dose of suspending disbelief and just hanging on for the ride, but it is a smutty good time.
